MoviePy – 视频文件剪辑的 FPS
在本文中,我们将了解如何在 MoviePy 中获取视频文件的 fps 即帧/秒(帧速率)。 MoviePy 是一个用于视频编辑的Python模块,可用于视频和 GIF 的基本操作。帧速率是显示这些图像的速度,或者您“翻阅”书籍的速度,它通常表示为“每秒帧数”或 FPS。每个图像代表一帧,因此如果以 24fps 的速度捕获和播放视频,则意味着视频的每一秒显示 24 个不同的静止图像。
我们可以在下面给出的命令的帮助下加载视频文件剪辑
clip = VideoFileClip(file_name)
In order to do this we will use fps
attribute with the VideoFileClip object
Syntax : clip.fps
Argument : It takes no argument
Return : It returns float
下面是实现
# Import everything needed to edit video clips
from moviepy.editor import *
# loading video dsa gfg intro video
clip = VideoFileClip("dsa_geek.webm").subclip(0, 10)
# getting frame rate of the clip
rate = clip.fps
# printing the fps
print("FPS : " + str(rate))
print("---------------------------------------")
# showing final clip
clip.ipython_display()
输出 :
FPS : 29.97002997002997

Moviepy - Building video __temp__.mp4.
Moviepy - Writing video __temp__.mp4
Moviepy - Done !
Moviepy - video ready __temp__.mp4
另一个例子
# Import everything needed to edit video clips
from moviepy.editor import *
# loading video gfg
clip = VideoFileClip("geeks.mp4")
# getting subclip from it
clip1 = clip.subclip(0, 7)
# getting frame rate of the clip
rate = clip1.fps
# printing the fps
print("FPS : " + str(rate))
print("---------------------------------------")
# showing final clip
clip1.ipython_display()
输出 :
FPS : 60.0
